Title: Timepiece with sound signaling function
Inventor: YAMAGUCHI YOSHITO
IPC: G10L13/02
Filed: 1985-09-30
Abstract: PURPOSE:To signal the time when external noise is getting smaller and the passing min from the time signal by giving a selection circuit selecting sound data read out of a sound ROM and a restart circuit signaling the time when noise is getting smaller. CONSTITUTION:When external noise is larger, an AND gate 84 is opened because the output signal of a noise detecting circuit is 'H', whereas an AND gate 86 is closed. When an external switch is operated, an output 48a comes to 'H', and is inputted to the set input S of FFs 90, 68 and 80 through an AND gate 84. The output Q is considered to the 'H'. When the output Q of the FF90 comes to 'H', an AND gate 72 is opened. When the inverse of the output Q comes to 'L', a reset passing time counter 32 is released, and starts counting. The output Q of the FF68 comes to 'H', whereby a sound signal generator circuit 38 starts its action. Since a code signal in a standby code ROM28 is outputted to the sound signal generator circuit 38 at that time, a sound is emitted from a pronunciation circuit 40.

Filed: 1987-08-31
Abstract: PURPOSE:To improve wear resistance and traveling durability without degrading electromagnetic conversion characteristics by incorporating platy inorg. powder and carbon black into the inorg. powder of a back layer and specifying the thickness of the back layer. CONSTITUTION:The back layer is constituted by dispersing the planar inorg. powder having 10-50 platy ratio and the inorg. powder contg. the carbon black and has <=1.5mum thickness. The platy ratio is the ratio of the particle size to the thickness of the powder (particle size/thickness). The wear resistance is thereby improved without degrading the electromagnetic conversion characteristics and the running durability is improved without increasing the coefft. of friction. The chipping of the back layer by traveling friction is decreased.

Title: Misfire detecting apparatus for multicylinder internal combustion engine
Inventor: HASHIGUCHI YUKIHIDE
IPC: F02P17/12
Filed: 1991-08-29
Abstract: PURPOSE:To detect misfire positively without affected by acceleration or deceleration by obtaining the estimated fluctuation value of the deviation caused by the acceleration or deceleration based on the angular acceleration of the crank shaft between cylinders, and correcting the detected deviation or a preset value. CONSTITUTION:A crank angle part 12 is arranged at a rotor 11 of a crank shaft 10 of an internal combustion engine 1. A top dead center sensor 16 is arranged at a rotor 15 of a distributor 13 so as to face the crank angle part 12. The output pulse of the sensor is sent into an electronic control unit 20. In the unit 20, the present crank angle and the engine speed are computed based on the input. Then, the elapsed time required for the specified crank-angle rotations of the shaft 10 at the time of combustion in each cylinder is detected. The deviation of the elapsed time between a certain cylinder and a cylinder, which is two ignitions ahead, is computed. When the deviation exceeds the preset value, it is judged that the cylinder is misfire, and the alarm is issued. At this time, the estimated fluctuation value of the deviation caused by the acceleration or deceleration of the engine 1 is obtained. The detected deviation or the preset value is corrected with the estimated value, and the influence of the acceleration or deceleration is removed. Thus, the occurrence of the misfire and the misfired cylinder can be positively detected.

Title: Installing mechanism for solar heat collector
Inventor: OKUYA KOUICHIROU
IPC: F24J2/52
Filed: 1982-12-13
Abstract: PURPOSE:To enable the constant stable fixation of a solar heat collector which is installed for use on a roof, even when the wind blows up. CONSTITUTION:A hole 9 for providing a connecting device for fitting a fixation wire is made in the end of a fixation-wire fitting arm 6. Numeral 10 denotes the fixation wire. By adopting such a construction, the jointing point of the fixation wire 10 to a supporting frame 2 can be set at a positions as high as required from the floor surface of the supporting frame so that the relation between the strength angle thetaT of the fixation wire 10 and an angle theta of fitting a heat collector is thetaT>theta. When a force FW blowing the collector upward acts with the wind so that it rotates the supporting frame around the supporting point D of the rear leg of the supporting frame, a force FM which acts in parallel to a line connecting the jointing point C of the rear frame member of the frame to the fixation wire with the supporting point D is necessitated on the front frame member side so as to counter the rotation of the frame, and a tensile force F is generated in the fixation wire to meet this necessity. This construction thus secures the stability of the frame, and accordingly it can prevent the heat collector from being unsteady when a strong wind blows, and the consequent damage of the collector and a roof.
